Gleadly Posted April 16, 2013 Share Posted April 16, 2013 Water is a conductor but not as good as copper and metals. Electricity's main aim in life is to go to earth. If you become a way for the electricity to get to earth you will get a shock. Bathrooms are dangerous places for electricity as there are a lot of pipes and things that go to earth. Electricity can go through you water and down to earth. You make the circuit as you are mainly water you make a very good conductor. The worst kind of shock to get is from an appliance they need DC current to run DC means direct current. This current has usually in say a washing machine has been through a transformer and a diode rectifier in the machine to correct the AC alternating current that comes through the mains to DC this is the electricity that will kill you no messing especially if the current goes down the left side of your body. This will stop your heart and you will die. Mains electricity is AC. This is alternating in other words it pulses on and off very fast. This can give you chance to basically get free from the pull of the electricity,so from a mains shock depending on where and what side of your body the electricity enters your body you have a good chance of surviving a mains shock. I was a TV repairman for many years and I have had many mains power shocks and I am still here. . A bit long for one sentence. Have punctuated it for you.

So technically. You can mess with 'some' types of electricity and not get it right 100% of the time, and survive! Link to comment Share on other sites More sharing options...
Obelix Posted April 16, 2013 Share Posted April 16, 2013 Just trying to correct a few things and putting it over without getting technical and geeky. Er yes, I'd have to disagree considerably I'm afraid. Water is an insulater - drinking water typically is about 0.0005 S/m. You don't conduct eletricity inside the body because of it's water content, you conduct electricity because of your ion content. Most appliances that run DC generally do so at a lower safe voltage. High voltage loads are generally AC, are isolated from the controlling switch and hence the control switch is safe to touch even with wet fingers. The heart is not on the left side of the body, it's in the center of the chest. The worst shock you can have is actually from one hand to the other as this goes across the chest cavity and the heart. Shocks down from one hand to ground through the feet are much less risky - not risk free to be sure, but far safer. These risk though assume you have actually grasped a bare conductor. Just flicking a switch with wet hands means that the water has to permeate the switch and provide the main conductance path from the conductor to your skin. In this situation the resistance is much higher and consequently the risk much less. ---------- Post added 16-04-2013 at 10:52 ---------- So technically. You can mess with 'some' types of electricity and not get it right 100% of the time, and survive! How many people have died for example from touching a torch battery - even with wet fingers..? Household mains voltage is safe to work on live, provided that you know what and why you are doing things. Electricity doesn't really become always lethal until you get into the kilovolt level.

Well maybe but its not a good idea to mess with eletricty its the amperage in the electricity that interrupts the signal pulses from your brain.it basically interrupts and destroys the minute electricity in your heart,DC is the one you don't want a shock from.it basicaly over rides all the electical functions of your dody,any thing in the house like a hoover or a washing machine has a AC to DC transformer in it they are deadly to get a shock from.

No it's not. ---------- Post added 16-04-2013 at 11:00 ---------- Well maybe but its not a good idea to mess with eletricty its the amperage in the electricity that interrupts the signal pulses from your brain.it basically interrupts and destroys the minute electricity in your heart,DC is the one you don't want a shock from.it basicaly over rides all the elitrical functions of your dody,any thing in the house like a hoover or a washing machine has a AC to DC transformer in it they are deadly to get a shock from. OK, first of all a transformer changes voltages, it doesn't do rectification. Washing machines and hoovers will have an AC motor in, they are very very unlikely to have a DC motor due to the weight, cost, and inefficiency of a DC motor. Seriously where are you getting this stuff from? Link to comment Share on other sites More sharing options...

Seriously where are you getting this stuff from? No they don't have an AC motor in them the voltage is corrected to run the motor on DC.the voltage goes through transformers to transform it to the different voltages needed in the appliance, the mains AC is rectified in the power supply panel by the bridge rectifiers.
